Is the inciting incident becoming a cyborg or inheriting the memories?

If it is becoming a cyborg then how does that alert him to a threat to the human race? If it is inheriting the memories in the process of assimilating to the cyborg collective (ala the Borg collective from Star Treck) and through that he learns of the threat. The inciting incident needs to be specified as the memory inheritance not becoming a cyborg this will also save space in the logline.

And as DPG asked the threat needs to be specified then we can imagine the action the MC will take to prevent it.

Its confusing to read that he needs to eliminate his kind from earth. Who tasked him with this? Why does he need to eliminate his kind? Will he eliminate himself as well? Are the renegades the ones he needs to eliminate or all his kind renegade and conformist alike?
Are the renegades the bad guys? Are all his kind the bad guys? Is the mother of his son the antagonist?

There are too many questions raised in an already unusual premise and the story dosn’t come across from the logline mostly because it doesn’t paint a clear image of what the MC will do in this story.

Perhaps starts with an inciting incident and work from there or better yet figure out the climax of the story and work backwards to the inciting incident. Once you identify the inciting incident you will be able to specify the action the MC will take in the story.

I suggest you re draft this logline to include an inciting incident then the MC’s action then the antagonist.

Hope this helps.
